I have seen the price for fuel pump module for about $200.00 NEW. How difficult is it to replace the fuel pump?
Hey guys.
After reading about your problems with all of your fuel tanks I thought I might share some info with you all. I had the same problem when I had my GMC Jimmy. As it turns out I guess the reason this problem is common with GM vehicles is not GM's fault. Awhile ago the gas companies started using a new additive in gasoline. It was suppose to help MPG in most vehicles, but after awhile, people realized that their fuel gauge would go on the fritz like all of you are experiencing. Turns out after they looked into it, the additive they used in the gas would eat away at the seals in the tank around the floater. So the guage would never read accurately. GM was the only company to use this particular material, so GM owners were the only ones to experience it. So if you bought your truck used or even if you've had it for awhile, the first owner may not have decided to fix it since it didn't affect driving. Just thought you all should know. The problem isn't in your truck, it's in the fuel tank.
